American society is not nap (午睡)friendly . In fact , says David Dings , sleep specialist at the University of Pennsylvania School of Medicine , “There’s even a prohibition (禁止) against admitting we need sleep”. Nobody wants to be caught napping or found asleep at work . To quote a proverb : “Some sleep five hours , nature requires seven , laziness nine and wickedness(淘气的) eleven.”
The way not to fall asleep at work is to take naps when you need them . “We have to totally change our attitude toward napping ,” says Dr. William Dement of Stanford University , the godfather of sleep research .
Last year a national commission led by Dement identified(发现) an “American sleep debt” which one member said was as important as the national debt . The commission was concerned about the dangers of sleepiness : people causing industrial accidents or falling asleep while driving . This may be why we have a new sleep policy in the White House . According to recent reports , President Clinton is trying to take a half---hour snooze (瞌睡) every afternoon .
About 60 percent of American adults nap when given the opportunity . We seem to have “a mid afternoon quiet phase ,” also called “a secondary sleep gate .” Sleeping 15 minutes to two hours in the early afternoon can reduce stress and make us refreshed . Clearly , we were born to nap .
We superstars of snooze don’t nap to replace lost shut--eye or to prepare for a night shift . Rather , we “snack” on sleep ,whenever , wherever and at whatever time we feel like it . I myself have napped in buses , cars , planes and on boats ; on floors and beds ;and in libraries ,  offices and museums .

We all have ideas about what kinds of foods are good to eat. We also have ideas about what kinds of foods are bad to eat. As a result, people from one culture often think the foods that people from another culture eat are nauseating(令人作呕的).When the famous boxer Muhammad Ali visited Africa, for example, one member of his group became quite sick when he saw someone pick up a butterfly and eat it. Many people would find it disgusting to eat rats, but there are forty-two different cultures whose people regard rats as appropriate food.
 Food likes and dislikes do not always seem related to nutrition. For example, broccoli is first on a list of the most nutritious common vegetables, but it is twenty-first on a list of vegetables that Americans like most to eat. Tomatoes are sixteenth on the list of most nutritious vegetables, but they are first on the list of vegetables that Americans like most to eat.
But dislike is not the only reason why some cultures will not eat a certain food. In some cultures, certain foods are taboo. Some foods are taboo in certain religions, but there are also other food taboos that are not connected to a religion. We do not usually think about why certain things are taboo in our culture. We may not even know why they are taboo. Anthropologists(人类学家) try to discover the hidden reasons for taboos.
Anthropologists believe that most food likes and dislikes are a result of the ways of life of different people. Some people live in areas where there are both large animals and many insects. It is difficult for these people to kill large animals, and it requires a lot of energy. It is easier for them to use insects for food because it is not difficult to catch insects and it does not require a lot of energy. Nomadic(游牧的) people who move around will not want to keep pigs for food. People will not eat pets such as dogs. Americans eat a lot of beef because there is plenty of land for raising cattle and the meat can be shipped cheaply for long distances by railroads.

D．Because cattle are large animals.
Smoking, which may be a pleasure for some people, is a series of discomfort for their fellows. Medical scientists have expressed their concern about effect of smoking on the health not only of those who smoke but also those who do not smoke. In fact, non-smokers who take in the air polluted by tobacco smoke suffer more than the smokers themselves. A great number of students are trying to persuade the university to forbid smoking in classrooms. Believe they are completely right in their aim. However, I think it more important to achieve this by calling on the smokers to use good judgment and to show concern for others. Smoking is not allowed in theaters, cinemas and in other public places. Therefore, smoking must be forbidden in our classroom. Although many people have passed away for having smoked a lot and we call on people to give up smoking, yet many more that are following will turn down what we say every day, above all, the young people smoke a lot more.
小题1: In the writer’s opinion, smoking does good to ________.
A．nobodyB．some peopleC．smokersD．young people
小题2: The phrase “pass away” probably means ________.
A．leave one’s homeB．lose one’s lifeC．pass byD．go away
小题3:According to the selection, which of the following is true?
A．Smokers suffer from the polluted air more than the non-smokers.
B．Non-smokers suffer from the polluted air more than the smokers.
C．Non-smokers suffer as much from the polluted air as the smokers.
D．Non-smokers don’t suffer so much from the polluted air as the smokers.
Think about what you had for lunch: Was it a hamburger? A chicken sandwich? Barbecue? What about vegetables? Would it surprise you to learn that what you eat can affect the whole planet?
It can—in a big way. New studies show how food and its production affect the globe and its warming climate. You’ve probably heard of global warming : The temperature is on the rise because humankind has been releasing (排放) amounts of gases into the atmosphere. One of these greenhouse gases is carbon dioxide（二氧化碳）.
What does this have to do with food ? A big part of the carbon dioxide that we put in the atmosphere every year comes from the process of making and eating food. The production of meat contributes a lot of that carbon diode. And much of meat’s contribution comes from beef , which is responsible for releasing even more warming gases into the atmosphere.
The process of making a hamburger ,for example, requires a lot of energy. A cow has to be fed and raised on farmland, and cow waste is a major source of methane (沼气) — an especially powerful greenhouse gas. The cow has to be killed. The meat has to be processed (加工) and shipped to a shop, which takes fuel . Most of the cow won’t even be used for meat that people eat. By the time a hamburger finally lands on a dinner plate, it has made a heavy effect on the environment.
We can reduce the production of global-warming gases by eating less beef .Other kinds of meat like pork and chicken do less harm to the environment—at least in terms of the amount of greenhouse gases released. 
All kinds of meat are harder on the planet than vegetables. To grow and eat a pound of potatoes, for example, sends less than one-quarter pound of carbon dioxide into the air. So changing our diet to less meat and more vegetables, as it turns out, may do the world some good.

In terms of history, Australian cuisine（烹饪）was on the basis of traditional British cooking brought to the country by the first settlers．Modern Australian cuisine，however．has been heavily influenced by Australia’ s Asian and Southeast Asian neighbors．The trend，encouraged by long-term government health programs，is towards low-fat healthy cookery including low-fat meat and lightly cooked，colorful，steamed or fried vegetables．Besides，1ike many English families，in many Australian homes，a widespread tradition of having roast turkey，chicken，and ham for Christmas 1unch or dinner still remains．
Generally breakfast is light in most parts of Australia．but in the colder regions porridge or meals similar to the full English breakfast may be consumed．In recent years，however，most Australian people prefer light breakfast in order to control their weight．The 1ight breakfast commonly consists of cereals（谷类），toast and fruit．A heavier breakfast will frequently include fried bacon，eggs，mushrooms，etc．Drinks taken at breakfast include tea，coffee，milk or juice．
The evening meal is the main meal of the day for most Australians，and when consumed at home，it is often eaten with members of the immediate family．The dishes served will vary widely according to the tastes and background of the family．A typical Australian restaurant might offer sandwiches，chicken or other meat-based dishes and cakes．
In recent years，take—away food is becoming popular in Australia．American-style chain restaurants are common including Subway，KFC，and Mcdonald’s．They a11 come from America．Most of these restaurants sell high quality food at reasonable prices．
With the high 1evels of immigration（移民）from the Middle East．South and Southeast Asia．Korea．China and other countries from a11 over the world to Australia．many authentic（正宗的）and high-quality restaurants are run by first-and second-generation immigrants from these areas．

Recently the World Health Organization announced that the disease of
smallpox（天花）had almost been wiped out in most parts of the world, thanks to widespread vaccination（种牛痘）. Most people are vaccinated at least once in their lives and if they wish to travel from one country to another they must be able to prove that they have had a recent vaccination. In this way the disease has been prevented from spreading and today one seldom hears of it at all.
This is mainly because of the great discovery made by a village doctor, Edward
Jenner, in about 1798 when he published his report of his new experiment called vaccination (from the word ‘vacca’ meaning a cow). Jenner discovered that people who worked with cattle often suffered from a harmless disease which they caught from the cattle, but these people never seemed to get smallpox. So he experimented by putting the disease into a small opening on the arms of healthy people, and though their arms became painful for a day or two, they soon recovered and none of these people ever got smallpox.
So the news of the wonderful discovery spread to other countries and people
rushed to their doctors to be vaccinated. In many countries the simple way to deal with the arm was done on thousands of people, and the terrible smallpox began to disappear.
71．Vaccination against smallpox has been so successful that _________ .
A．the discoverer made a large amount of money
B．Dr Jenner was given a prize by the World Health Organization
C．smallpox has almost disappeared in most countries
D．smallpox was no longer in existence on earth
72 ．Smallpox has been prevented from spreading through the following measures EXCEPT that ________.
A．most people were vaccinated against the disease at least once
B．people going abroad should promise not to spread the disease
C．people travelling from one country to another must prove they are vaccinated
D．people must be vaccinated shortly before going to foreign countries
73 ．What led Dr Jenner to experiment with vaccination was that ________ .　
A．he wanted to make a great discovery and publish it
B．vaccination could make people's arms safe
C．he tried to cure the farmers of some disease caught from the cattle
D．those who worked with cattle seemed free from getting smallpox
74．The doctor's new discovery was called ‘vaccination’ for the reason that ________ .
A．he discovered smallpox near a farm
B．he experimented with a disease from the cattle
C．he was working with cattle in the countryside
D．people got the disease of smallpox from the cattle
75．The news of the discovery ________.
A．caught people's attention from all corners of the world
B．spread far and near in the western countries
C．made people rush to Dr Jenner for vaccination
D．helped to get rid of the terrible disease of smallpox
A super drug that could remove Alzheimer’s (老年痴呆症)，heart disease and diabetes (糖尿病) and help people live to 100 is being developed by scientists. Their research is based on the identification of three genes that help prolong lives and prevent diseases which occur in old age. Medically controlling the proteins made by the “ longevity genes” will allow millions to live longer, predicts Dr Nir Barzilai.
Those whose DNA strongly features the three genes are 80 percent less likely to develop Alzheimer’s. The genes also fight against the deadly impact of smoking, poor diet, obesity and lack of exercise.
Already, several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage old age. “ The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing,” he said.
Of the three longevity genes, two genes increase the production of so-called good cholesterol(胆固醇), which reduces the risk of heart disease. The third prevents diabetes. They were discovered by Dr Barzilai’s team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the group, which shared relatively few common ancestors, was 20 times more likely to hit the entury. Dr Barzilai said: “ 30 percent of them were obese or overweight and 30 percent smoked two acks of cigarettes a day for more than 40 years, however they can live to 100.”
But Andrew Ketteringham of the Alzheimer’s Society said: “Alzheimer’s disease, a most common disease, is likely to be caused by a combination of genetic disosition(遗传倾向), lifestyles and life events. Many genes are probably involved.
小题1:Some people are able to live to 100 years because of ______.
A．a magical medicineB．three special genesC．good living habitsD．longevity proteins
小题2:Why does the discovery of the longevity genes mean a lot?
A．Because it can bring great benefits to scientific labs.
B．Because it can help people change their unhealthy genes
C．Because it helps produce a drug that can make people live longer.
D．Because it will help scientists build up a new branch of biology.
小题3: From Paragraph 4 we can infer that ________.
A．longevity genes can create good cholesterol.
B．the volunteers share some common ancestors
C．bad habits are likely to have no effect on the volunteers
D．longevity genes protect the volunteers against bad habits
小题4:What is Andrew Ketteringham’s attitude toward the study?
A．PositiveB．NegativeC．CriticalD．Cautious

Chocolate might lower your chances of having a heart problem. According to a new study, a new study, a small amount of chocolate every day could decrease the risk of having a heart attack, by nearly 40 percent, German researchers followed nearly 20,000 people over eight years, sending them several questionnaires about their diet and exercise habits. They found people who had an an average of six grams of chocolate a day—or about one square of a chocolate bar—had a 39 percent lower risk of a heart attack.
Previous studies have suggested dark chocolate in small amounts could be good for you, but this is the first study to track its effects over such a long period. Experts think the flavonols（黄酮醇）contained in chocolate are responsible. Flavonols, also found in vegetables and red wine, help the muscles in blood vessels（血管）widen, which leads to a drop in blood pressure. “It’s a bit too early to come up with recommendations that people should eat more chocolate, but if people replace sugar or high-fat snacks with a little piece of dark chocolate, that might help,” said Brian Buijsse, a doctor at the German Institute of Human Nutrition in Nuthetal, Germany, the study’s lead author.
The people tracked by Buijsse and colleagues had no history of heart problems, had similar habits for risk factors like smoking and exercise, and did not vary widely in their Body Mass Index（身体质量指数）.
Since the study only observed people and did not give them chocolate directly to test what its effects were, experts said more research was needed to determine the candy’s exact impact on the body. Doctors also warned that eating large amounts of chocolate could lead to weight gain. “This is not a prescription（指示）to eat more chocolate,” said Robert Eckel, a professor of medicine at the University of Colorado who is not linked to the study. “If we all had (a small amount of)chocolate every day for the rest of our lives, we would all gain a few pounds.” Eckel said it was amazing to find such a small amount of chocolate could have such a protective effect, but that more studies were needed to confirm its conclusions.
1．What is the main purpose of the article?
A．To suggest people eat as much dark chocolate as possible.
B．To warn people not to eat too much chocolate.
C．To tell people how to avoid a heart attack.
D．To report on a study about the benefits of chocolate.
2．Both Buijsse and Eckel believe that        .
A．dark chocolate in enough amounts could be good for our health
B．eating large amounts of chocolate could lead to weight gain
C．we can cure our heart problems with dark chocolate
D．we’d better not advise people to eat more chocolate at present
3．Which of the following statements about the study is FALSE?
A．It’s the first time that the effects of dark chocolate has been examined.
B．The researchers followed nearly 20,000 people for over eight years.
C．The researchers didn’t give any diet instructions to the people followed by the study.
D．The study found that eating about six grams of chocolate a day was beneficial.
4．We can infer from the text that         .
A．eating a small amount of dark chocolate will lower your blood pressure
B．scientists are now certain of the effects of dark chocolate
C．eating a little chocolate over a long period will not lead to weight gain
D．Flavonols can only be found in dark chocolate and red wine
Raising pets is not a new thing in China , but recently it has taken on a new meaning .
As a famous Chinese saying goes, pursuit of petty (小的，不重要的) pleasures weakens one’s will to make progress . The saying has been so popular that even today many people still consider raising pets as a hobby of the idle .
Things have changed much recently and now raising pets has become a popular pastime , resulting in a successful pet care industry .
Pet food is sold in almost all supermarkets and many special stores for pet needs have been set up .
Animal hospitals provide various medical services for sick dogs and cats , and pet exchange fairs are held regularly .
At the China International Pet Show which took place recently in Beijing , more than 100 factories from across the country exhibited their products . Thousands of dealers and pet owners went to the show.
“People’s swollen pockets make it possible for many to raise pets , a hobby that used to be enjoyed only by the wealthy ,” said Wang Wei , who works with the National Kennel Association of China .
Wang Yuyan , vice president of the Small Animals Protection Association , agreed , “ In many films and novels , having a pet is used as a symbol of wealth . That’s not a complete picture . ” Wang added that pets are friends in a real sense of the word , not just playthings . “ Anyone with a loving nature can raise pets . ”
Still the high cost of keeping a pet is something many people have to think about .
“I like dogs and cats , but I have neither time nor money to raise them , ”said Li Jun , in her 40’s , a civil servant from Beijing .
The cost of raising a dog is high in Beijing , where registration (登记) is a must for all dogs and costs 5,000 yuan for each animal . In addition , pet owners must pay for regular injection of vaccines (疫苗). Most of all , dog food is quite expensive .
Unlike his mother , Li Jun’s 10-year-old son, Li Qiyu, dreams of the day he will have his own pet . “I hope I can have a dog in my house , ” he said .
小题1:Things have changed much recently , because ___________ .
A．people have all become kind-heartedB．small animals have no places to live in
C．people’s living conditions are improvingD．more and more people are out of work
小题2: In big cities in China today , raising pets ________ .
A．has changed people’s lifeB．has destroyed some families
C．has met much difficultyD．has brought much business for some people
小题3:According to Wang Yuyan’s opinion , raising pets _________ .
